Description

Allow log syntax like

log"${MDC(CONFIG, SHUFFLE_MAPOUTPUT_MIN_SIZE_FOR_BROADCAST.key)} " +
  log"(${MDC(MIN_SIZE, minSizeForBroadcast.toString)} bytes) " +
  log"must be <= spark.rpc.message.maxSize (${MDC(MAX_SIZE, maxRpcMessageSize.toString)} " +
  log"bytes) to prevent sending an rpc message that is too large."
